1. The key effect of outdoor headlamps
Outdoor headlamp (in short, outdoor applications wear on the head of the lamp, is the release of the hands of the lighting special tools. In the case of walking at night, if we hold a strong light flashlight, one hand will not be free, so that when there is an accident, it will not be able to deal with properly. So. A good outdoor headlamp is something you should have if you are walking at night. By the same token, if we camp at night, wearing LED headlights can free up our hands to do a lot of work.
2. Common batteries for outdoor headlamps
Alkaline batteries are the most common battery. Its electromagnetic energy is higher than that of the lead battery; alkaline batteries can’t be charged and only reach 10% to 20% of the output power when it is in the ultra-low temperature of 0F; the Voltage of the battery decreases obviously when it is applied.
(Nickel-Cadmium batteries) : Rechargeable battery more than a thousand times, it can maintain a certain application of output power, it can not and partial alkali battery storage electromagnetic energy comparison, in the ultra-low temperature 0F still has 70% of the output power, the whole process of rock climbing is best with high efficiency energy battery it is 2 ~ 3 times higher than the standard battery.
Lithium battery: it is 2 times higher than the general battery electromagnetic energy voltage, a lithium battery of 2 times the picoampere/hour above the 2 alkali battery, in 0F similar to indoor temperature application, but more expensive, its operating voltage can hold stable. It is especially useful in highland areas.
3, outdoor headlamp 3 key performance index value
As an outdoor headlamp must have the following three key performance index values:
1 Waterproof headlamp, in the wild camping walking or other night work inevitably encounter rainy days, so the outdoor headlamp must have waterproof, otherwise a rainy day or soaking will cause short circuit resulting in out or light and dark, dark night lead to safety risks. Then, when buying LED headlamps, it is necessary to recognize whether there is a waterproof mark, and it must exceed the waterproof level above IXP3. The larger the data, the better the waterproof performance (the waterproof level will not be repeated here).
2. Fall resistance, a good performance outdoor headlamp must have fall resistance (impact resistance), the general detection method is 2 meters height to width ratio will fall down without how to destroy, in outdoor activities may also be due to wear too loose and other reasons to slip off the situation, if the fall caused by the housing split, battery fall down or internal circuit failure, Even in the dark to find the fall of the battery is a very scary thing, so the LED headlamp is certainly not safe, so when buying to recognize whether there is a sign of anti-fall, or understand the store of the LED headlamp anti-fall.
3. Cold resistance, the key for outdoor sports in North China and its plateau areas, especially the LED headlamp of the separated battery box, if the outdoor headlamp of the shoddy PVC cable is selected, it is likely to cause the cable skin to harden and become brittle due to the cold, and then cause the fracture of the internal core, so if you want to apply the outdoor headlamp at ultra-low temperature, Be sure to double the attention to the product’s low temperature design scheme.
